Incentive Mechanism Design For Mobile Hotspot Sharing Networks

The era of “Internet of Everything” is coming soon,the number of mobile devices and some other sensor devices is experiencing a dramatically growth,thus the global mobile data traffic is exploding.However,as the main provider of mobile network connection services,as to say the cellular networks are beyond the reach of the rapid growth of mobile data.At the same time,many devices in the huge Io T network,especially those whose energy are constrained,lack the efficient network connection paradigm.If one networking based on mobile hotspot sharing is used,large-area network coverage can be efficiently realized.The basic idea of the networking paradigm is to activate some mobile nodes in the cellular network(such as the holders of smart phones and other smart devices)to switch on their mobile hotspots,and provide Wi-Fi hotspot connections or other connections for resource-constrained nodes.The communication requests of the restricted nodes enable efficient access to the mobile Internet.In this networking model,how to encourage mobile users to contribute hotspots is a key issue.Although there are some research results for hotspot sharing,the incentive mechanisms in these research results almost all based on centralized control,and the hotspots are mostly fixed hotspots,and there has been no one considering the actual situation of the communication node.How to design an efficient networking paradigm and consider incentive mechanism is what we will do in this research issue.This paper mainly studies the network scenario where hotspot sharing is performed between multiple mobile nodes under the control of a single operator.A new network model based on evolution game theory is proposed.The behavior of the subscribed user nodes and the payoff of the operators in the mobile hotspot sharing network are systematically studied.Based on the detailed mathematical description of the behavior of mobile nodes,the regularity of network evolution is obtained.Based on this,numerical simulation analysis is carried out to prove the feasibility of mobile hotspot sharing network from theory and experiment.On the basis of feasibility,a set of distributed incentive mechanism based on two-stage game is designed.Under the action of incentive mechanism,the evolutionary game process and network equilibrium state of mobile nodes are studied.The incentive mechanism designed in this paper includes two parts: data flow price based on usage and free traffic reward.This incentive mechanism ensures that the network can operate normally and operators can also get revenue from it.Through simulation and contrast experiments,it is verified that the proposed networking method based on mobile hotspot sharing and distributed incentive mechanism can improve network performance,and achieve network offloading while providing efficient network access for resource constrained nodes.In summary,this paper proposes a networking mode and provides a distributed incentive mechanism for mobile hotspot sharing networks,and proves the feasibility of networking mode and incentive mechanism based on simulation results,and provides a theory for mobile hotspot sharing and related research.
